Title: Method and circuit arrangement for transmitting television signals
Inventor: VOLLMER RUDOLPH DR
IPC: H04N19/50
Filed: 1988-02-03
Abstract: For purposes of signal generation it is appropriate to transmit television signals in digitised form over long transmission links. If the television signals comprise components in digital and analogue form as is the case, for example, in D2 MAC signals, it is required also to digitise the analogue signal components, in this case the image content signals. This, however, results in an unsatisfactory utilisation of the available transmission networks for which certain standards have already been determined. The invention provides a remedy in this case and leads to considerably better utilisation of the available transmission networks. This is done by subjecting the image content signals to a data reduction. In this process, only the differences between adjacent pixels are transmitted instead of the absolute values for the luminance and chrominance values of the pixels. Since these differ little from one another in conventional original images, the invention manages with fewer data for restoring the original image content signals. <IMAGE>

Title: Method of constructing a tunnel, in particular a traffic tunnel, and shield driving machine for carrying out the method
IPC: E21D11/10
Filed: 1988-03-16
Abstract: The invention relates to a method of constructing a tunnel, in particular a traffic tunnel, in which the tunnel cross-section is driven with a shield driving machine and in each case a section of a steel tunnel lining, in particular corrugated sinusoidally in the longitudinal direction of the tunnel, is set in the area of the shield tail, and then the annular space formed between the shield tail and the set section is sealed off and grouted with mortar, and during the advance of the shield tail the clearance space resulting in the process is grouted with mortar. To simplify and accelerate the method, after the setting of a new section of the tunnel lining, a pipe located above the section set beforehand, allowing the mortar to pass through and forming a seal on the outside with a trailing seal of the shield tail is to be advanced before the consolidation of the mortar and independently of the shield tail while maintaining the seal with the trailing seal until the pipe forms a seal with the front end area of the set section, whereupon the shield tail is advanced until its trailing seal forms a seal with the front end of the pipe, and finally the annular space is to be grouted.

Title: Movement device for motorised telescopic antennas
Inventor: FERRETTI NERINO
IPC: H01Q1/10
Filed: 1988-05-24
Abstract: In the case of known motor-operated telescopic antennas, their tension cables and their guides are subject to severe wear, which can lead to the tension cables breaking and to destruction of the drive motor, which is frequently blocked in consequence. It is intended that the novel device should no longer have the indicated disadvantages. The tension cable (1) of the telescopic antenna has offset, lateral notches (6) and engages in a tension coil (2) having a double tooth system which is displaced and offset in the form of beams, and said cable (1) hooks into a toothed wheel (gearwheel, pinion wheel) (3) by means of an elastic intermediate piece (4). The novel device has the advantages that the tension cable of the telescopic antenna can easily be fitted and hooked in. Winding up and unwinding take place more uniformly than in the past, so that blocking of the drive motor is largely suppressed. <IMAGE>

Abstract: A viewing optics for armoured vehicles, such as surveillance periscope or telescopic sight, has a mirror head which protrudes from the vehicle superstructure, has an integrated viewing mirror and produces an optical connection between a viewing opening and a light passage opening aligned at right angles thereto. The light beam bundle leaving the light passage opening reaches, via a corresponding perforation in the vehicle superstructure, at least one optical system incorporated in the vehicle superstructure, such as day sight equipment, night sight equipment, or laser range finder. So that the required perforation in the vehicle superstructure is as small as possible and the production costs for the viewing optics are as low as possible, a reflective input objective is arranged in the mirror head, which consists of an oblique mirror and a deflection unit. The oblique mirror is arranged above the viewing mirror, and the latter is aligned with the oblique mirror in such a manner that the viewing opening is imaged via the input objective in the light passage opening.

Patent DE-3830896-A1 (DE)
Title: Device for a dual-chamber canister
Inventor: SCHIEMANN WOLFRAM DIPL ING DR
IPC: B65D1/04
Filed: 1988-09-10
Abstract: In a dual-chamber plastic canister, the relatively thin connecting strip 42 in the manner of a film hinge extends between the chambers 12 and 13 as previously in the separation plane, but it is curved at least over a substantial distance in the course from the top to the bottom in the side view of the canister. A dimensional rigidity is thus produced, as a result of which the two chambers 12 and 13 cannot pivot towards one another so easily. This therefore obviates the need for shaping the handle on both chambers for the purpose of stabilisation, thus simplifying the manufacture. <IMAGE>

Title: Method for adjustment of the mixture control in internal combustion engines
Inventor: MUNZ ULRICH
IPC: F02D41/12
Filed: 1988-10-27
Abstract: The departure for the present invention is a method for adjustment of the mixture control in internal combustion engines, in which a set of pilot control characteristics set up by the intake air quantity per unit time and/or the throttle valve angle and the speed of the internal combustion engine supplies a pilot control variable determining the quantity of fuel to be fed to the internal combustion engine. In load operation of the internal combustion engine the said variable is multiplied at least by one correction variable, adaptable as a function of the mean value for the control variable of the control unit of a superimposed fuel-air ratio control. In overrun conditions of an internal combustion engine with overrun cut-off fitted in a motor vehicle, the said correction variable is increased as a function of the time elapsed from the commencement of overrun cut-off.
